Bis(4-aminopyridinium) bis(hydrogen oxalate) monohydrate
Abstract
In the title compound, 2C5H7N2+·2C2HO4−·H2O, the asymmetric unit consists of an aminopyridinium cation, an oxalic actetate anion and a half-molecule of water, which lies on a two-fold rotation axis. The crystal packing is consolidated by intermolecular O—H...O, N—H...O and C—H...O hydrogen bonds. The molecules are linked into an infinite one dimensional chain along [010].
